In SegCorr: Detecting Correlated Genomic Regions

Description Details Author(s) References See Also Examples

Performs correlation matrix segmentation and applies a test procedure to detect highly correlated regions in gene expression. The segmentation procedure detects changes in the patterns of the gene expression correlation matrix. The test procedure asseses which regions exhibit a significantly high level of correlation. Additionally, a preprocessing procedure is provided to correct gene expression for copy number variation.
